A quick glance at the dates on this blog's posts will reveal that it has been idle for about 3 years. During that time, I've been teaching and, most recently, have been ill. To paraphrase Iain Banks, I am unofficially (as few care) rather poorly. But this enforced physical idleness has rekindled interest in some of my blogs that have been languishing in cyber-storage: Aakom is one such blog.
